Which term refers to the key structure that includes management plane components which are network-enabled and remotely accessible in cloud computing?

The term that refers to the key structure including management plane components that are network-enabled and remotely accessible in cloud computing is the "Metastructure." This term specifically encompasses the overarching management systems, protocols, and interfaces that enable the control and configuration of cloud services. In cloud environments, the management plane is critical as it allows for the remote management of resources, facilitating tasks such as monitoring, provisioning, and maintaining cloud assets.

While infrastructure primarily deals with the physical and virtual resources (servers, storage, network) used to provide cloud services, and architecture outlines the conceptual structure and underlying technology stack, metastructure accurately captures the remote access and management capabilities that are vital for effectively operating in a cloud environment. The framework can refer to a more general set of practices or guidelines but does not specifically denote the management capabilities as closely as metastructure does. Thus, "Metastructure" is the most fitting term for this specific aspect of cloud management.
